2 SAFETY INSTRUCTIONS 1 Caution The following safety precautions must be observed during all phases of operation, service and repair of this equipment. Failure to comply with the safety precautions or warnings in this document violates safety standards of design, manufacture and intended use of this equipment and may impair the built-in protections within. Delta Elektronika shall not be liable for user s failure to comply with these requirements. 2 Installation Category The Delta Elektronika power supplies have been evaluated to installation category II (Over voltage category II). 3 Grounding of Mains Input This product is a safety Class 1 unit. To minimize shock hazard, the unit chassis must be connected to the AC Power Supply mains through a three or four conductor power cable for respectively a single or three phase unit, with the ground wire firmly connected to an electrical ground (safety ground) at the power outlet. For units designed to be hard-wired to supply mains, the protective earth terminal must be connected to the safety electrical ground before another connection is made. Any interruption of the protective ground conductor, or disconnection of the protective earth terminal will cause a potential shock hazard that might cause personal injury. 4 Grounding of Power Output If the output of a unit is specified to deliver maximum 60VDC, and either the negative or positive power output is grounded, the voltage on the power outputs and sense connections can be considered safe. Warning: When the positive DC power terminal can exceed 60VDC in respect to the negative DC power terminal, additional external measures must be taken to ensure safety isolation of the DC power terminals and sense connections. Warning: When the negative power output of the unit can exceed 60VDC / 42.4Vpk in respect to ground, additional external measures must be taken to ensure safety isolation of the DC power terminals and sense connections. The standard LAN, USB and Interlock connectors and optional interfaces are at ground level and can be considered safe if the negative DC power terminal of the unit does not exceed 1000VDC / 707Vpk in respect to ground. Caution 1: If a low voltage unit has both power outputs floating, or if the output is in series with an external high AC or DC voltage, the negative power output can exceed the safe value in respect to ground as specified in the above warning! Caution 2: Although a high voltage unit is set to a safe voltage below 60VDC, for safety it must always be considered as high voltage unit! Wrong operation, a programming error or an external defect can result in an unsafe high output voltage. For more information and schematics regards Grounding and Safety, see the special application note "Safe operation of a power supply" on the Delta Elektronika website. 5 Danger of electrical shock Touching the contacts of the mains plug or wires directly after disconnecting from the mains can cause an electrical shock. See next paragraph "Connection to the mains supply". 6 Connection to mains supply Either connect to the mains supply permanently or via an industrial type plug, complying with IEC 60309. "Permanently connected equipment" or "Pluggable equipment type B". 7 Fuses Fuses must be changed by authorized Delta Elektronika service personnel only, for continued protection against risk of fire. 8 Input Ratings Do not use an AC Supply which exceeds the input voltage and frequency rating of this unit. The input voltage and frequency rating of the Delta Elektronika power supply series are stated in de accompanying datasheet. 9 Live Circuits Operating personnel must not remove the unit cover. No internal adjustment or component replacement is allowed by non Delta Elektronika qualified personnel. Never replace components with the power cable connected. To avoid injuries, always disconnect power, discharge circuits and remove external voltage sources before touching components. 10 Parts Substitutions & Modifications Parts substitutions and modifications are allowed by authorized Delta Elektronika service personnel only.

To con fig ure the sim u la tion in ter face, the power sup ply must be con nected to the net work via LAN. 6 PHOTOVOLTAIC SIMULATION CONFIGURATION PARAMETERS To simulate a photovoltaic curve some reference parameters are required. These parameters are often specified by manufacturers of photovoltaic panels. The parameters required for the simulation in ter face should be val ues un der stc. Stc specifies a temperature of 25 C and an irradiance of 1000 W/m2 with an air mass 1.5 (am1.5) spec trum. Fig ure 3-3 shows an ex am ple pho to vol taic curve with the relevant parameters names. see table 4-1 for an over view of all reference parameters that are required. To sim u late a pho to vol taic curve based on the ref er ence parameters described above, some panel parameters are required. These parameters are specified in Table 4-2. DYNAMIC EFFICIENCY TEST The sim u la tion mod ule can run a dy namic mppt ef fi ciency test as spec i fied in the EN50530 an nex B. To run this test ex tra parameters are required. These parameters are specified in table 4-3. The dy namic ef fi ciency test uses the same con fig u ra tion parameters as described in chapter, but varies the irradiation levels of these parameters specified in Table 4-3. TABLE MODE The sim u la tion in ter face also sup ports a ta ble mode. With this ta ble mode it is pos si ble to sim u late a cus tom curve. Or sim u late a photovoltaic curve existing of multiple panels in series where some pan els are shaded. In ta ble mode the sim u la tion mod ule uses a ta ble of 128 data points to pro gram the cur rent of the power sup ply. It is pos si ble to cal cu late a par tially shaded pho to vol taic curve with the desk top ap pli ca tion. The re sult ing ta ble can be ex ported to a csv (comma sep a rated value) file. Cus tom or cal cu lated ta bles are pro gram ma ble via the desk top application. DESKTOP APPLICATION All the parameters required for photovoltaic simulation can be con fig ured us ing the desk top ap pli ca tion which is sup plied on a CD with the sim u la tion mod ule. The CD can also be down loaded from http://www.delta-elektronika.nl/ When the ap pli ca tion is started, it will show the wel come screen, it will query a list of power sup plies with a sim u la tion in ter face installed. Se lect the power sup ply form the drop down list and con nect. Or en ter a IP ad dress and con nect. Se lect the de sired sim u la tion type af ter this and click start, af ter which the corresponding application will start. Figure 4-4 shows the wel come screen. In the photovoltaic simulation the parameters for the photovoltaic simulation can be configured. The application also renders the pho to vol taic curve cal cu lated with the en tered val ues. It reads the volt age and cur rent mea sure ments of the power sup ply and dis plays these in the graph. Fig ure 4-5 shows the Pho to vol taic Simulation application. To cal cu late a new pho to vol taic curve, en ter all re quired pa ram e ters and click Cal cu late. If one of the pa ram e ters changes in the window, the calculation will automatically take place. The sim u la tion mod ule in the con nected power sup ply stores the pa ram e ters in its mem ory, to get these pa ram e ters click Load. When you ac cept the fol low ing di a log, the pa ram e ters from the simulation module are filled in the application. To store new pa ram e ters in the sim u la tion mod ule, click Write. The new pa ram e ters are now stored in the sim u la tion mod ule. The sim u la tion mode can be changed un der the Tools sec tion of the menu bar. In the Pho to vol taic Sim u la tion win dow these modes are Sin gle Panel, Mul ti ple Pan els and Dy namic ef fi ciency. When the sim u la tion mode is changed, the out put of the power sup ply is switched off. In Sin gle Panel mode, it is pos si ble to simulate a single photovoltaic curve.

In Mul ti ple Panel mode, cal cu la tion of an ar ray of pan els is pos si ble. In Dy namic ef fi ciency mode, it is pos si ble to start a dy namic efficiency test. Be sure to store the new ref er ence pa ram e ters and dy namic test set tings to the simulation module before starting the dynamic efficiency test. 7 Ta ble sim u la tion The simulation interface can simulate a cus tom curve based on a ta ble as de scribed in chapter. A separate application is available specifically for this mode. With this ap pli ca tion it is pos si ble to man age, load and write ta bles from and to the simulation interface. The ap pli ca tion can read csv files. To use this fea ture please use the fol low ing for mat: The col umns must be sep a rated by a comma (,). The rows must be sep a rated by a new line. The first row must con tain In dex, Volt age and Cur rent in that or der. The first in dex must con tain zero for ei ther the volt age- or the cur rent set tings, where the last in dex must con tain zero for the opposite. The volt age val ues can only in cre ment or dec re ment in value for the whole ta ble. See the ex am ple in ta ble 4-4. fig. 4-4 Welcome screen 8 In ter nal re sis tance sim u la tion The simulation interface can simulate an internal resistance with a maximum value depend ing on the type of power sup ply. The set tings for the in ter nal re sis tance can be con fig ured trough the web in ter face. Within the interfaces page. The internal resistance simulation is very sensitive to high ca pac i tive loads. A slow set ting is avail able in the web in ter face if the simulation is unstable. The internal resistance simulation is a correction of any other pro gram ming source. For ex am ple you can set the volt age and cur rent with the front knobs, set an in ter nal re sis tance value trough the web interface, and the simulation interface automatically corrects the output voltage. 9 Leadless sens ing sim u la tion The simulation interface can automatically compensate for volt age drops over the leads with out us ing sense leads. This simulation type has three different modes: Cal cu late re sis tance: In this mode the re sis tance of the ca ble is calculated by means of the materials electrical resistivity, length and the cross sec tional area. Mea sure volt age drop: In this mode the user must mea sure the volt age on the out put ter mi nals of the power sup ply, the volt age on the ter mi nals of the load, and the cor re spond ing current. Mea sure re sis tance: In this mode the user must mea sure the re sis tance of the leads. All these op er at ing modes are lim ited by the max i mum configurable resistance as specified. The set tings for the leadless sens ing sim u la tion can be con fig ured trough the web in ter face. Within the in ter faces page. The leadless sens ing sim u la tion is a cor rec tion on any other pro gram ming source. For ex am ple you can set the volt age and cur rent with the front knobs, set a leadless sens ing re sis tance value trough the web in ter face, and the sim u la tion in ter face automatically corrects the output voltage. fig. 4-5 Pho to vol taic Sim u la tion Index, Voltage, Current 0, 36.96, 0.000 1, 36.95, 0.069 2, 36.93, 0.139......... 125, 28.00, 8.661 126, 26.50, 8.731 127, 0.00, 8.800 ta ble 4-4 rev.

SM3300 INTERFACES 5 UNIT CONFIGURATION The unit will au to mat i cally de tect the new in serted in ter face. The in ter face icon will be shown in the dis play, see fig 6-4. For pro gram ming the volt age and/or cur rent via the in ter face, set the cor rect source for CV and CC re spec tively, see be low example: none 0.0V none 0.00A int Menu Lock on/off For ex am ple the in ter face is mounted in slot2. To pro gram the CV-set tings via this in ter face, via the front menu go to CON FIG U RA TION -> SOURCE -> Vsettings and set it to Slot2. To pro gram also the CC-set tings via this in ter face, go to CON FIG U RA TION -> SOURCE -> Isettings and also set it to Slot2. In stead of do ing this via the Front Menu, the source can also be set via the web in ter face or via Ethernet com mands if the unit is con nected to the net work via LAN. 6 SERIAL PROGRAMMING The unit can be pro grammed by us ing the se rial pro gram ming com mands. See ta ble 4.1 for an over view of the avail able commands. To start, first the com mand "CH n" must be ex e cuted to ac ti vate the in ter face by set ting its chan nel num ber (ad dress). The vari able n is a num ber be tween 1...32. For ex am ple "CH 1". The com mand "CH?" que ries the chan nel of the ac tive se rial interface. For more de tails about the com mands in ta ble 6.1, re fer to chap ter 5 of the pro gram ming man ual for Ethernet & Se quencer. The man ual is stored in side ev ery SM3300 unit and can be down loaded via the web in ter face. It can also be down loaded from www.deltapowersupplies.com. 7 PROGRAMMING SPEED Pro gram ming from a low to a high out put volt age is nearly load independent. Pro gram ming down to a low volt age takes more time on lighter loads. This is caused by the out put ca pac i tors, which can only be dis charged by the load be cause the power sup ply can not sink current. With the op tional Power Sink, also the pro gram ming down speed is nearly load independent. With op tional high speed pro gram ming, the rise and fall time is 5 to 25 times faster. Note that with this op tion. the out put rip ple is higher. 8 MONITORING VIA SERIAL INTERFACE Via the pro gram ming com mand "MEA SURE:" the volt age, cur rent or power can be mon i tored. See the man ual 'Ethernet & Se quencer Pro gram ming SM3300' for de tails. Note: on a pul sat ing load, the cur rent and power mon i tor ing will not ex actly match the out put cur rent and power. This is mainly caused by the cur rent through the out put ca pac i tors. 9 TROUBLE SHOOTING Check the pro gram ming source is set to the cor rect slot. Check the out put is switched ON, the In ter lock is con nected and Re mote Shut Down is low. The first pro gram ming com mand must be "CH n" oth er wise the in ter face will not be ac ti vated. Check that the com mu ni ca tion is work ing; "*IDN?" must re turn a value. En sure to end the query with the ter mi na tion char ac ter LF. (LF = 0x0Ah in ASCII) Note: the se rial in ter face uses the '.' (dot) as the dec i mal sym bol and not the ',' (comma). Check if your pro gram is us ing the set tings in Microsoft Win dows re gional set tings. Ei ther change your pro gram to spe cif i cally use the '.' or else change the dec i mal sym bol to '.' in your re gional set tings (from the control panel). Check that the power sup ply's out put is not lim ited. Con sult the SM3300 man ual about ad just ing the limit set tings. fig 6-4 Po si tion of the in ter face icon in the unit dis play.

The out put cur rent can eas ily be mea sured us ing the I-mon i tor (see fig. 8-6). The range 0-5V or 0-10V can be se lected by ethernet com mand only. See ethernet pro gram ming man ual for fur ther de tails. Note that the mon i tor out puts are float ing with re gards the power out put (sim i lar to sig nals from the ISO AMP). The mon i tor out puts are buf fered with op-amp s and pro tected with series resistors and parallel zenerdiodes. The ta ble on page 1-2 of the in ter face datasheet shows the impedance levels of the monitoring outputs. The mon i tor ing out puts can drive a me ter di rectly (fig. 8-6). Note: on a pul sat ing load, the cur rent mon i tor will not ex actly match the out put cur rent. This is mainly caused by the cur rent through the output capacitors. 9 STATUS SIGNALS The sta tus out puts have a sep a rate Ø con nec tion (pin 8) to avoid un wanted off sets in the pro gram ming. All the sta tus out puts are logic out puts. Logic "0" means the out put is 0 V, logic "1" means the out put is 5 V. This makes it pos si ble to drive di rectly: an opto-coupler, a TTL gate or a CMOS gate. The Limit Sta tus or LIM-sta tus is "1" in case the out put volt age or cur rent reaches the limit set ting.
